Stomatia margine flnuato. 
!The Jinuated-edged Stomatia . 
This is the larged fpecies of this genus; it is four inches in length, and near three 
in breadth at the broader end, and is near an inch in height in the moil elevated 
part: the upper furface is of a very deep chocolate colour, variegated with white ; it 
is full of obtufe, undulated ridges, which are of a pale and almoil whitifh colour on 
their fummit, and of a deep purpliih brown on the iides, as is alfo the intermediate 
part of the ihell: the infide is of a pale brown, with a tinge of a violet red 5 the 
fpiral turn at the head is fmall, and the edge is all the way round-finuated, the depref- 
iions running between the extremities of the elevations. 
It is found on the coail of Malabar, and no where elfe, fo far as is yet known : few 
fpecimens of it have yet got into Europe, and mod of thofe are in Holland. 
The other fpecies of the Stomatia are, i. The fmall, purple, fmooth Stomatia. 
2. The fmall, brown, undulated, and ridged Stomatia. 3. The larger, lmootb, pur¬ 
ple Stomatia, with fine flriae. 
DENTALIUM. 
f"T“^ H E Dentalium is a fimple fhell, having no hinge, and formed only of one 
f piece: it is of a figure approaching to cylindric or conic, and is fometimes 
crooked, fometimes firaight; fometimes clofed at one end, fometimes open at. both : 
the animal inhabiting it is a nereis. 
The name Dentalium has been given to this genus, from the great refemblance fome 
of the fpecies have to the dentes canini of animals : they have alfo been called Antales 
' and Entalia by fome, and by many, from their tubular form, Tubuli marini. 
Dentalium fubcylindricum, Jlriatum, et annulatum. 
'The fubcylindric, flriated, and annulated Dentalium. 
This is a fingular fhell \ when mod perfed, it has much the appearance of a frag¬ 
ment only of fome of the other fpecies: it is about two inches in length, and of the 
thicknefs of a fwan’s quill; it’s colour is a greyidi-white, often, but not always, varie¬ 
gated with green, fometimes with a tinge of reddifh : it has about ten deep, longitu¬ 
dinal furrows running all the way down it’s outer furface, and the ridges between 
them are rounded ; there are ufually alfo three annules or circles palling round at une¬ 
qual didances, and interrupting, but not wholly dilcontinuing, the longitudinal furrows; 
the (hell is thin, and eafily crulhed or broken. 
It is common on the fhores of Italy, and in fome other parts of Europe. 
Dentalium conicum, inflexum, lave. 
The fmooth, crooked, conic Dentalium . 
This grows to about an inch in length, and to the thicknefs of a fmall goofe-quill: 
the figure is conic, larged at the mouth or opening, and thence becoming gradually 
fmaller to the point, where it is (harp, and has no opening : the whole external fur¬ 
face is fmooth, and naturally polidied 5 and the colour is a fine bright white, like that 
of the fined porcelain j fometimes, but more rarely, it is tinged with purple, fome¬ 
times with a bright red or brown. 
It is frequent on many of the coads of Europe, and is alfo common to the Ead and 
Wed Indies j vad quantities are wafhed on fhore on the coad of Portugal. 
Dentalium conicum, inflexum, Jlriatum, et faf datum. 
The conic, crooked, Jlriated, and faf dated Dentalium . 
This is a confiderably large fpecies; it grows to four inches in length, and to the 
thicknefs of a child’s finger: the larged part is at the opening, or mouth, and it 
thence becomes gradually fmaller to the other extremity, where it is terminated by a 
fharp point, without any perforation 5 it is not draight, but lightly curvated : it’s fur-
